Frostbite scars


Hello Doctor: A few days ago, my skin came into contact with the metal frame of a -80 degree freezer for several seconds, resulting in redness, swelling, and pain.
The next day, a dark brown discoloration appeared.
I would like to ask if this will leave a scar.
Thank you!

It is possible, but without actually seeing the lesion, it cannot be confirmed.
If it is very bothersome, please seek medical attention as soon as possible.

More Info


Frostbite is a serious condition that occurs when skin and underlying tissues freeze due to prolonged exposure to extremely cold temperatures. The severity of frostbite can vary, and it is classified into degrees, similar to burns. The initial symptoms often include redness, swelling, and pain, which can progress to numbness and discoloration as the tissue becomes more severely affected. In your case, the deep coffee color you are observing is indicative of tissue damage, and it is crucial to understand how this might affect your skin in the long term.

When frostbite occurs, the skin can be damaged in several ways. The outer layer of skin (epidermis) may be affected first, leading to redness and swelling. If the frostbite is more severe, it can penetrate deeper into the dermis and even affect subcutaneous tissues. The discoloration you are experiencing could be due to blood vessel damage or tissue death, which can occur in more severe cases of frostbite.
Regarding your concern about scarring, it is important to note that the potential for scarring largely depends on the severity of the frostbite. Mild frostbite may heal without any lasting effects, while more severe cases can lead to complications such as:
1. Blisters: These may form as the skin heals, and if they become infected or are not properly cared for, they can lead to scarring.

2. Tissue Necrosis: In cases where the frostbite is severe enough to cause tissue death, this can lead to significant scarring or even the need for surgical intervention, such as debridement or amputation in extreme cases.

3. Changes in Skin Texture and Color: Even if the skin heals, it may not return to its original appearance. Changes in pigmentation or texture can occur, leading to a scar-like appearance.

To minimize the risk of scarring, it is essential to take appropriate care of the affected area. Here are some recommendations:
- Seek Medical Attention: If you haven't already, consult a healthcare professional. They can assess the severity of your frostbite and recommend appropriate treatment.

- Keep the Area Clean: Proper hygiene is crucial to prevent infection, which can exacerbate scarring.

- Moisturize: Use a gentle, fragrance-free moisturizer to keep the skin hydrated. This can help with the healing process.

- Avoid Picking or Scratching: Allow the skin to heal naturally without interference, as this can lead to further damage and scarring.

- Follow Up: Regular follow-up with a healthcare provider can help monitor the healing process and address any complications early.

In conclusion, whether frostbite will leave scars depends on the severity of the injury and how well it is managed. While mild cases may heal without any lasting effects, more severe frostbite can lead to scarring and changes in skin texture. It is crucial to seek medical advice and follow proper care protocols to minimize the risk of complications. If you notice any signs of infection, such as increased redness, swelling, or pus, seek medical attention immediately.
